Good for the merchants/business. Bad for CC companies, and anyone that benefits from points/rewards.
Be very careful about these types of proposals. The Durbin Amendment was supposed to help reduce fees, but wound up doing the opposite for many small businesses. Visa, MC, Disc, and Amex have very high priced lawyers and bean counters looking for loopholes.
For those who know about the Durbin Amendment, the goal was to reduce debit card interchange rates. It actually had the opposite effect for most small businesses. The Durbin Amendment put a cap on the fees allowed for debit card transactions. These fees were/are still variable. But since there's a max cap, merchants are now usually charged the maximum allowed.
Prior to the Durbin Amendment, small merchants usually paid a smaller fee for pin debit transactions. The opposite happened, where most small businesses were now charged more for pin debit transactions.
Larger businesses did benefit, but I'm not crying for the C-suite if Wallyworld or Target pays a little more in fees. I do feel bad for the smaller businesses, the mom & pops that suffered from this badly thought out legislation.
